 288 <h1>Welcome to CBFW</h1>
 289 Welcome to CBFW, I cant find my configuration file so im assuming you installing me for the first time<br>
 290 If this is not correct then we have a big problem that needs to be solved, i hope you have a backup of the old
 291 config, cause that will make life easier.<br><br>
 292 However, if this is the first time you have run this app, then all is good with the world. All I need right
 293 now is a place where i can store my config. I search the following directories for the location of my
 294 configuration (webconfig)<br>
 295 <li> /var/run/glcas/
 296 <li> /var/lib/glcas/
 297 <li> <?php echo $underroot?>/var/glcas/
 298 <br><br>
 299
 300 As root, you must now create one of these directories and change the ownership of the directory to the web owner.
 301 (chown <?php echo $uid?>:<?php echo $gid ?> the_path_you_choose).<br>
 302
 303 Now, tell me where you want me to create the webconfig file:<br>
 304 <form method="post">
 305 <select name="installdir">
 306 <option value="/var/run/glcas">/var/run/glcas</option>

 308 <option value="<?php echo $underroot?>/var/glcas/"><?php echo $underroot?>/var/glcas/</option>
